Please note that this article is intended for educational purposes. Do not attempt to test the battery yourself. We suggest taking your battery to someone who knows inverters and batteries thoroughly.

They will be able to check your battery for problems and replace it before it worsens!

  1. Fully charge the battery: The initial step in this process is to be sure that you’ve recharged the battery of your inverter before you can conduct a maintenance inspection.
  2. Unplug the battery from the inverter: Once you have confirmed that the inverter’s battery has been fully charged, turn off the inverter, disconnect it from the power source, and then disconnect your battery to the inverter.
  3. Ensure that the terminals are clean: Make sure there aren’t any layers of battery terminals. Inverter batteries produce lead sulfur. The build-up makes the current route through the battery more prone to damage, which could result in your system’s power requirements not being met or, in some cases, worse. This can be removed using a nylon brush and warm water.
  4. Verify the levels of acid for the proper operation of your battery inverter: It is vital to ensure a consistent level of acid throughout the cells. Each cell is opened and then filled with distilled water up to the maximum amount above.
  5. Check the colour of the acid: Take the float indicators off and examine the colour of the acid using the hydrometer. If you find dark brown or black-coloured liquid, your battery might be damaged or near the end of its life. If it’s colourless, it’s healthy.
  6. Control the voltage: Test the battery’s voltage using a voltmeter/multimeter with an active probe of the multimeter to one end of the battery’s terminal and one negative probe on the opposite side of the terminal for the battery. When the battery’s voltage rises to higher than 11.9 Volts, then it’s in good condition. If it is lower than 10 volts, it suggests a problem with the battery.
  7. Specific Gravity: Check the specific gravity by utilising a hydrometer to determine how much electrolyte is specific to it within every cell. The fully charged battery should have an SG read of 1.240 or greater.
  8. Check for loose or damaged Connections: Check the battery’s wires for damage or melts in the insulation. The exposed or damaged wire may affect not just the output of your battery but may also increase the risk of short circuits and other risks within your home.
  9. ENSURE that your surfaces are clean: To ensure that your battery is operating well, make sure you check for dirt that may be on the surface. If you find any dirt, you can use a clean cloth to clean it off and ensure that the battery is clear!
